I've run into a little problem, neither of the cargo bays work, or are even interactable. I culled all of my mods down to the newest versions of SP+, FAR, and Firespitter and still no go on the cargo bays opening/closing, which IIRC is pretty big regarding trying to make functional aircraft with FAR installed. I am wholly at a loss as to what the cause is, and I've been working upwards of an hour on it. On an unrelated note, great mod, great to see it added to stock. Fits quite well and as a spaceplane junkie I quite love it.
